Guello stuck in Lower Dorn Mines
Guello is stuck in the Lower Dorn mines after clearing out the salamanders and their leader, Shikata. I can talk to Guello and receive healing from him but he won't go back to the Gnome Village. No Svirfneblin/Gnomes remain in the mines but a bunch are walking around the village and I'm able to converse with them (at least the ones that still have their tongues
The "Rescuing Guello" quest is listed under "Done Quests" in Journal, Chapter Six. When I speak with Beorn in the Gnome Village, his dialogue reads "Thank you for rescuing Guello from the Mines. His return has bolstered our spirits greatly."
I'm running IWD:EE Update 184.108.40.206 (21 August 2018) on Windows 7 Pro SP1.
